摘要
阐述了高精度磁测在单县龙王庙地区铁矿调查评价中的应用,高精度磁测的目的是分解早期1∶5万航磁异常,细致反映龙王庙地区磁异常的分布,为该区的铁矿调查评价和成矿预测提供了基础资料。以近年来的高精度磁测工作为基础,该区铁矿深部找矿取得了重大突破,勘查发现了大刘庄大型沉积变质型铁矿,并进行了富有价值的成矿预测,显示出了良好的地质效果。
Applicaion of high - precision magnetic survey in investigation and assessment of iron ore in Longwanmiao area in Shanxian county has been described in this paper. Application of high - precision magnetic survey aims to break down magnetic surveying anomaly with the scale of 1 ： 50000 in early period, reflect distribution of magnetic anomalies in Longwangmiao area in detail, and provide basic information for investigation and evaluation of iron ore predication in this area. Based on high- precision magnetic survey work in recent years, ore exploration in deep part of iron deposit in this area has achieved a major breakthrough. Liujiazhuang sedimentary - metamorphic iron deposit with large scale has been found, ore- forming valuable predication has been carried out, and has gained a good geological effects.
